• Quantum wire
• Second harmonic generation
• Third-harmonic generation

In present work, we have studied second and third-harmonic generation (THG) in a quantum wire with parallelogram cross section. An analytic expression for THG is obtained using a compact density matrix approach and an iterative procedure. According to results the maximum THG can be obtained by optimizing confinement potential. Structural parameters have a great influence on THG in this system. Finally, electric field effect on second harmonic generation (SHG) and THG has been studied. Results show an increase of electric field, enhancing the peak values of SHG and THG.
